Abstract

Lithium Niobate (LN) and Quartz. crystal are good piezoelectric crystals, they can be used bases of surface acoustic wave (SAW) devices. In this paper, SAW elemental equation and corresponding mechanics boundary condition equation are deduced. For the above two crystals, SAW velocities are calculated systematically, and curves of the acoustic reciprocal velocity are drawn using a new circle iterative method in decoupling acoustic sagittal plane, that is yz plane. Calculation results lay a good theoretical base for design of SAW devices and have research signification and practice value.
